We're dividing 210710 by 10 
We want to figure out the number of times 210710 can be divided by 10.

Advancing to step 1:
2 divided by 10 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 10

Let's proceed to step 2:
If we divide 21 by 10, we get 2 and a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 20 from 21 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 10

Let's proceed to step 3:
10 goes into 10 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 10 from 10, we get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 10

Step 4:
10 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 210.0
Subtract 0 from 7 to get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 10

Step 5:
10 goes into 71 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 2107.0
Subtracting 70 from 71 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 10

Let's proceed to step 6:
The number 10 fits into 10 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 21071.0
Subtract 10 from 10 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
The number 10 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 21071.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
10 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 21071.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 21071.0, with a leftover of 0.0.
